This invention relates to metallic saddles or sills for the door openings of either swinging or sliding doors, and has for its general object to provide a metallic door saddleor sill embodying a plurality of elements which may readily be combined in various difierent relations to afford a saddle or sill. of practically any desired width, either w thout grooves in instances where the door or doors is or are of the swinging type, or with one or any desired plurality of grooves to accommodate the door or doors when the latter is orare of the sliding type. f

A special object of the invention is to provide the saddle or sill elements with interfitting formations permitting quick, easy and firm interconnection of the elements in vari ous different relations without the use of screws, bolts, rivets or other auxiliary fastening devices.

Another special object of the invention is to provide the saddle or sill elements with interfitting formations which are strong and sturdy and which areof such design as to permit economical production of the elements.

With the foregoing and other objects in view, whichwill become more fully apparent as the nature of the invention is better understood, the same consists in the novel constructions and combination and arrangement of features as will be hereinafter more fully described, illustrated in' the accompanying drawing and defined in the appended claims.

In the drawing, wherein are illustrated certain practical embodiments of the invention, and wherein like characters of reference denote corresponding parts in related views:

Figure8 is a view similar to Figure A illustrating'a pair of grooved door guide elements combined with each other andwith the wear plate shown in Figure 5.

Referring to the embodiment of the inventionillustrated in Figures 1 andQ, A designates the wear plate, B, B a pair of approach plates, and C an edging plate, each of which may be formed from any suitable material such, for example, as bronze, into any deslred length and width and of anydesired thickness or weight to afford requisite strength and to provide for wear.

As illustratedfin Figures 1 and 2 a pair of ribs 10, 10 project downwardly from the wearvplate A along the opposite side edges thereof, and, as is understood, these ribs are coextensive in length with the wear plate. Formed in each rib throughout the length thereof is a dovetail slot 11 which opens at its narrowest side through the bottom of the rib as shown.

The approach plates B illustrated in Figures 1 and 2 each includes a vertical web por tion 12 adapted to abut a side edge of the wear plate A, a horizontal flange 13 formed as an inwardly directed extension of the web 12 to underlie and form aseat forone of the ribs 10 of the wear plate, an approach flange 14: extending downwardly and outwardly from the top of the web 12, a stiffening rib 15 extending downwardly from the inner end portion-of the flange 13, and a tongue 16 of dovetail cross section projecting upwardly 1 therewith at the from the flange 13 to be received in the slot 11.

To assemble an approach plate 13 with the wear plate A at either side thereof, the two plates are placed in end to end relation with the tongue 16 of-the approach plate alined with the slot 11 in the related rib 10 of the wear plate and the plates then are moved relatively inward whereby the tongue is caused to enter the slot and thus interlock the plates together.

A number of wear plates A of different widths may be provided and an approach late B may be interengaged with any one of said plates in the manner stated at either or both sides thereof, Figure 1 of the drawing" illustrating an approach plate at each side of the wear plate, and Figure 2 illustrating an approach plateat one side only of the wear plate and an edging plate C interengaged opposite side thereof.

The edging plate C, which is adapted for use in instances where either or. both sides of the wear plate terminate flush or substantially' flush with a veritcal wall of a building structure, is understood to be coextensive j in length with the wear plate and in cross section comprises a vertical flange 17 adapted to lie against the side edge of the wear plate and the outer edge of the rib 10, a horizontal flange 18 formed as an inward extension of the lower portion of the vertical flange 16 to underlie and form a seat for the rib of the wear plate a finishing and reinforcing flange 19 formed as a downward extension 1 of the flange 17 flush orsubstantially flush with the outer face thereof, a reinforcing rib 20 formed as'a downward extension at the inner end of the flange 18, and a tongue 21- of dovetail cross section projecting upwardly from the flange 18 to be received in the slot- 11. Assembly of the edging plate with the 5 vention illustrated in Figures 3 wear plate is effected in the same manner as heretofore stated in respect to the approach plates B.

According to the embodiment of the inand 4:, one side of the wear plate A1 is formed the same as the wear plate illustrated in Figures 1 and 2, but the opposite side thereof, instead of v being provided with a downwardly directed rib having a dovetail groove therein, is pro- 1 vlded with a relatively narrow downwardly directed reinforcing rib 22 and with a horizontal flange 23 formed asan outward extension of said rib and provided on the upper face thereof with an upwardly directed tongue 24 0f dovetail cross section. Thus, the wear plate A1 is adapts to have interengaged therewith 1n the same manner as the approach and edging plates B and C are interengaged with the wear plate A, an auxiliary wear plate, designated as A2, of any suitable width and otherwise a duplicate of the wear plate A illustrated in Figure 1, the purpose of the auxiliary wear plate being to increase the width of the sill or saddle as is understood.

Since, as stated, the auxiliary wear plate A2 is to all intents and purposes a duplicate ofthe wear plate illustrated in Figure 1, it follows that the side thereof remote from the wear plate A1 may have interconnected therewith either an approach plate B or an edging plate C in the manner shown in Figures 1 and 2, respectively.

In instances where the saddle or sill is to be used in connection with sliding doors, such as the doors of elevators, and where it is desired to provide a door guide groove or grooves in the sill or saddle, the wear plate A, Alor A2 obviously may have the grooves formed directly therein, or groove elements of the type illustrated in Figure 1 and des ignated generally as D may .beformed for cooperation with either of said wear plates. The groove element I) illustrated includes a U-shaped groove forming portion 25 having horizontal outwardly directed flanges 26 provided with dove-tail slots 27, one of which is adapted to receive the tongue 24; of a wear plate A2 and the other of which is adapted to receive thetongue 16 or 21 of an approach plate B or'edging plate C, or the tongue of a suitablyformed connecting member for j oiningtwo of the. groove elements together.

Referring to the embodiment of'the invention illustrated in Figures 5 to 8, it will be observed that the wear plate A3, instead of being formed like the wear plates A, A1 and thereof with dovetail tongues 28, of substantially triangular shape in' cross section, and that the approach plates B1, edging plate C1, auxiliary wear plate A i and the groove elements D1 are formed with slots of the same cross sectional size and shape to receive said tongues. In other words, referring to Figure 5, it will be observed that the wear plate A3 is provided at each of the two lower, side corners thereof with a tongue 28 which projects both laterally outward and downward from the wear plate, and that'the upper and the inner edges of said tongue are directed downwardly and inwardly whereby the tongue possesses the duplex dovetail shape illustrated.

The approach plates B1 for use with the wear plate A3 each includes a vertical flange 29 and a horizontal inwardly directed flange 30, and at the junction of said flanges is formed an inwardly opening duplex dovetail groove 31 corresponding in sectional shape to the tongues 28. In addition, each approach plate is provided with a reinforcing and anchoring flange 32 extending downwardly from the horizontal flange 30, and with an approach flange 33 forming a downward and outward extension from the top of the vertical flange 29. Interconnection of the approach platesBl with the wear plate A3 is effected in the same manner as connection of the approach plates B with the wear plates A, A1 or A2; i. e., by alining the slots and tongues of said plates and moving the plates relatively inward.

The edging plate Cl illustrated in Figure 6 for use with the wear plate A3 is of the same construction as the approach plateB with the exception that the approach flange 33 is omitted and a vertical finishing flange 34 is provided as a downward extension of the horizontal flange 30 of the edging plate flush or substantially flush with the outer face of the vertical flange 29 of said plate.

As illustrated in Figure 7, the auxiliary wear plate A4 for use with the wear plate A3 is formed at one side in the same manner as either side of the wear plate A3; i. e., with a duplex dovetail tongue 28 at the lower, side edge thereof, but at its other side is formed similarly to the approach and edging plates B1 and G1 for interfitting engagement with the tongue 28 of the wear plate A3. That is to say, the latter mentioned side of the auxiliary wear plate is formed with a vertical flange 35 extending downwardly from the under side thereof inwardly from the edge of the plate, andwith a horizontal, outwardly directed flange 36 forming an extension of the flange 35 and provided with a down wardly directed reinforcing rib 8?. A duplex dovetail slot 38 is formed at the junction of the flanges 35, 36 and this slot is adapted to receive a tongue 28 of the wear plate A8 as shown. A number of auxiliary wear plates A4 of various different widths are provided and obviously either a second auxiliary wear plate or an approach or edging plate may be connected with the auxiliary wear plate shown.

In Figure 8 of the drawing is illustrated a pair of groove elements D1 for use with a wear plate of the type shown n Figures 5 to 8. These groove elements which are duplicates of each other each comprises a U-shaped groove forming portion 39 inclusive of the spaced vertical flanges 40, A0 from each of which extends outwardy a horizontal flange 41, and at the unction of each pair of said flanges the groove element is formed with a dovetail duplex slot 42 to receive the tongue 28 of a wear plate A8 or the tongue 28a of an auxiliary Wear plate A5 wh ch is the same in all essential respects as the wear plate A3 but of different width. Thus, a groove element D1 may be connected either with the wear plate A3 or the auxiliary wear plate A4 in the same manner as any one of the elements B1, C1 or A4, and by means of the auxiliary Wear plate A5 either a second groove element D1 or an approach or edging plate may be connected with the sill or saddle to provide a desired fin sh at the side thereof.

Obviously, various other shapes or e1ements than those illustrated may be provided for interlocking engagement with the sh apes or elementsshown and with one another in the samemanner as the shapes illustrated and ClBSCl1l38d,aDC1'ObVIOUSlY *too the various shapes-may-haveany desired finish,"the
